Research at Argonne centers around three principal areas: energy, biological and environmental systems and national security. Argonne develops transformational energy storage systems that enable and enhance electric-drive vehicles and a green-energy grid through electrical energy storage development, prototype and manufacturing process engineering, stationary storage and grid management, and electric transportation systems. Argonne is developing the next generation of alternative energy sources to promote energy independence through improved chemical fuels, advanced biofuels, and solar energy systems, as well as through the optimization of fuel and engine dynamics. Argonne develops advanced reactor and fuel cycle systems including fast reactor and fuel cycle technologies, advanced modeling and simulation methods, and innovative nuclear energy systems – to enable the safe and sustainable generation of nuclear energy.
